Thank you! That file should not be used in the game. I'll look into the issue this evening.

That png was used for the faces in the first game (The Wizard's Tower). Since I built this second project on top of that, probably there is some leftover, somewhere, maybe even in an unused map, that still points to the old faces. If I don't find the culprit I will just add the file back when I go back home.
